TIRE ARMOR.

Specification of Letters latent. Patented Sept. 14,1915.

a lication filed March 11, 1914. Serial No. 824,072.

To all whom it may concern: I

Be it known that I, PETER A. CHRISTEN- SON, a citizen of the United States, residing at Benson, in the county of S wift, State of Minnesota, have invented certain new and useful Improvements in Tire-Armor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tire armors, and particularly to armors for pneumatic tires for automobiles.

r The principal object of the invention is to provide more] means for lockingthe ends of thearmor together, and also novel means for drawing the ends of the armor together to engage the locking means. e

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 isan elevation of a fragment of a wheel and tire showing my armor thereon and in locked position,

Fig. 2 is a transverse section on the line 2-2 of Fig. 1, Fig. 3 is a vertical longitudinal section on the line 33 of Fig. 2, and Fig. 1

is a side elevation of'a fragment of the tire and armor showing the'operation of the means for drawing the ends of the armor together. a j

Referring particularly to the accompanying drawing, 10 and 11 designate respectively the end links of the'tire armor, each of the links being-formed with a ground engaging rib 12.. Slidably mounted "on the link 11 is a sliding plate 13 to which-is I secured a spring plate 14 which has its free end turned down as shown at 15. One end ofthis plate 13 and like-wise of the spring is bifurcated as shown at. 16, with the legs of the bifurcation embracing the adjacent rib 12. At the inner end of the plate is an upturned lug 17 which projects upwardly and supports the downturned endof the spring rearwardly of the downturned por tion. Secured on theupper side of the free end of the spring is a beveled ended projection 18 which extends slightly beyond the downturned end of -the spring. The rib of each of the other links of the armor di: verges at one end of the link, as indicated at 19, and passed through the diverging end as and through the rolled tongue 20 of the end ofthe adjacent link is a pivot pin or bolt 21. The end link 10 has an additional pair of openlngs 22 in thediverging portions of its r1b which received the inturned ends 23 of a yoke 24'. This .yqke is arranged to be engaged in an opening in-"the adjacent end of the next link.

In the operation of the device the armor is placed on the tire, and the end links placed in juxta-position. The yoke member is then engaged the divergent portion of readily engaged with and disengaged from the rib and the hook of the link engaged in the opening of the link of the other end of the armor. By rocking the lever,the link will be drawn so that the end links will be pulled together. Carried by the divergent portions of the rib of the link 10 is a trans- Verse-pin or bolt 29 which will engage the beveled end of the projection 18 and raise the spring 14, the said bolt then passing under the downturned end of the. spring and against the stop lug 17. Whenthe bolt engages the lug the spring 14 will drop and engage its downturned end at the other side,

of the bolt. The end links 10 and 11 will thus be securely fastened together. When I so fastened, the yoke and attached lever and link are renioved from the link 10. The

fact that the plate 13 is slidably mounted on the link 11 permits'a slight expansion (5f the rib of one of the end links having a transverse pin therein, .a plate slidably mounted on the-Vothe'r end link, a spring iatch member carried by thesIidabIe plate In testimony whereof, I afiix mj signafor engagement with the transverse pin of h b f d (11 k d b 1 ture, in the presence of two witnesses. t e e ore-mentione en in an a eve ed nose on the outer end of the spring latch PETER CHRISTENSON' 5 member for engagement with the said pin Witnesses:

to guide the latch into engagement with the O. A. CHRISTENSON, pin when the links are drawn together. M. A. OVEBLIE.
